How to connect printer to new router? Help!

[Seeingadistance]

I've switched to Vodafone for my home internet and can't get my printer's Wifi to connect. When I try setting it up using the Wizard on the Printer it asks for WPA/WEP and I don't know what that is, or where I would find it. Any ideas? It's not the Wifi password or the Web UI password - which are on the router.

Asked DH (Tecchy) and he says that WPA is the wifi password.
He also said (C&Pd)
There are different levels of encryption, if your printer only has wpa and wep and your router only allows wpa2 which is common for modern default on the routers you may have to change the allowed level to something like wpa2/wpa on the router in the wifi settings, which is probably set to wpa2-psk

Hope that makes sense?

I just change the router name and password to the old one, then everything just continues to connect without changing the logins for 101 devices.

We did this recently and worked out that some of our older devices couldn’t cope with the longer/stronger password on the new router. Too much faff to change the p/w again and relink the other devices so set up a guest network with a compatible p/w that worked.

Thanks for responses so far. I don't always understand the answers when I ask techy questions, but I'll have a go with a guest network.
